Will it charge a battery through a cigarette lighter if when the key is turned off, the cigarette lighter goes off?

Nope. The car needs a power outlet that stays on all the time. Just about all recent cars [at most 1999 to present] have an always on power outlet although it may take a while to find it.

The correct answer will depend on your vehicle. If your cigarette lighter gets continuous power even when the key is turned off, then the answer is YES. If the power to the cigarette lighter is cut off when the key is turned off, then the answer is NO. An easy way to test your cigarette lighter when the key is turned off is to plug something into it (i.e. USB charger or test the lighter itself) and see if it works.

No. Based on what your saying, with key off cigarette lighter is disconnected from the battery, it must connected to the battery to charge it.

I'm not sure what you mean. If you're asking if it will still work without the car being either on or on accessory, every car I've ever been in does maintain power to the cigarette outlet even when the car is completely off. If that doesn't work, just turn your car on accessory and it will work fine. You just turn the switch on the invertor on. I'd recommend turning the interior lights off in your car while doing this or run the cord through the window to prevent running the battery dead. If you do that, you won't have a problem with your battery going dead, not even close.

Normally the roulette in the vehicle is driven by the ignition switch which means it will shut off when you turn the key off. Even if the outlet stays on, it would take weeks for the LED on the charger to drain battery. It uses 5 volts and very little current.

In my car, the 'cigarette lighter' socket is powered on only when the key is in and turned to on or 'accessory', so it is not on. A blue LED indicates when the charger is getting power from the car, so it is easy to verify.

No it doesn't. Your vehicle needs to be running to charge the battery. You may use it with your vehicle off but not for too long

It probably will. Most cars will turn off the power to 12v socket when car is turned off. In that case there is no problem.

NO...this is a battery charger. You will need to dismount the battery and take it to a location where this is power for the charger to do its job.

If your lighter plug turns on and off with the ignition switch and you leave the power to the unit in the on position then yes.

It should. I attached it directly to my Jeep battery to provide a 12 volt source of power that would be available even when the ignition is off. We mostly use it to charge cell phones and camera batteries when we are camping

Robert the device plugs into your 12 volt adapter or cigarette lighter ...so there is always voltage there after you turn the car off I pull mine out a little so it does not make a connection that's the only way to disconnect from your battery. but there's no problem. I would highly recommend this product I love mine it is totally hands off thru your car speakers. Just like onstar

I do not have this charger anymore, but if I recall correctly: it will turn off. However as long as the battery is completely charged it is in my opinion just cosmetic. R.

I believe the answer is yes, but only if the cigarette lighter socket is hot when the ignition key is turned off. Some cars the lighter socket is "on" when the key is not in the ignition, some cars the lighter socket turns off with the ignition switch. I happen to have one car of each style.......

The voltage is wrong you need a 12v panel directly to the car battery. Most cigarette lighters are off when the key is out. The purpose of those panels is to keep the power up and defray the loss of power from the car not being started each week.

It will shut off, if your cig lighter shuts off when the key is off. The Ipod stays on for a while, until the auto shut off kicks in.

All depends on how you connect it. If you are using the power ports in the car, some shut off when the vehicle is turned off some do not. Mine is wired directly to the battery.

I assume your qeustion is if the product can be left connected while the car is off. I'd say yes, it will turn off I think. Although I haven't tried it. But in case the 12V port inthe car stays on it may drain the car battery since it has a fan that spins when connnected to power.

I can't say definitively but from empirical evidence I don't believe it does. The head unit goes dark when the car is turned off and I've never experienced a battery issue.
